Answer:
Step-by-step explanation:
2.5 = 5 * .5
1 = 1
70 = 2 * 5 * 7
LCM = 2 * 5 * 7
If you include the 1/2, you will reduce the LCM to 35, but 70 will be left out of the LCM.
Answer:
a²- b²=(a+b)(a-b)
a² + b²=(a+b)²-2ab or (a-b)²+2ab
(a + b)³=a³+3a²b+3ab²+b³ or, a³+b³+3ab(a+b)
Answer:
Hence the critical value for the right-tailed test is
. Since the test value is greater than the critical value so we reject the null hypothesis.
Step-by-step explanation:
Hypotheses are:
Here we have s_{1}=6800 and s_{2}=3900. Here we will use F -test. The Value of test statistics is
Here the degree of freedom of the numerator is
and The degree of the denominator is
The critical value for the right-tailed test is
. Since the test value is greater than the critical value so we reject the null hypothesis.
